About the Mp3player PCB

Mp3player is an open source ESP32 PCB design by ILikeMice, published on GitHub. It is a 2-layer board measuring 55.5 × 54 mm, with 65 components from 28 distinct parts.

Its main chip is the ESP32-S3-MINI-1, from the ESP32 family. Other key parts include the TPA6132A2RTER, BQ25170JDSGR, D3V3XA4B10LP, PCM5100A and CJ6109B33M. By type, the board carries 25 capacitors, 19 resistors, 6 ICs, 3 diodes, 2 connectors and 2 switches.

It belongs with the audio and power & battery designs in this gallery.

From the project

As the title might suggest, this is an mp3 player fully designed and made by me as my 2nd PCB project ever!! I thought itd be a cool thing to make and something not too difficult for a beginner!

- Main SoC: ESP32-S3-MINI Module - Audio Processing: - PCM5100A DAC - PA6132A2 Stereo Headphone Amp - 5 Buttons, all customizeable via firmware! - 0.96in display

Thats about all (not counting LDOs, connectors or other components ofc)!

Mp3player: common questions

What microcontroller does the Mp3player use?

The Mp3player is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the Mp3player PCB?

The Mp3player measures 55.5 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mp3player?

65 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mp3player design files?

From the ILikeMice/mp3player repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Mp3player design in my own project?

The repository has no license, so all rights stay with ILikeMice. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mp3player without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
